A high-energy explcding wire facility was used to investigate pinch effects in thin-walled aluminum tubing. The experiments carried out consisted of subjecting the tubing to the discharge of a 141-kj capacitor bank and observing its motion by flash radiography and by high-speed sequential photography. Each tube first imploded unifornfly, then broke down into an arc discharge in a manner similar to that of solid exploding wires. The implosion or pinch phase is adequately accounted for by the magnetic forces of the current discharge first acting against the mechanical strength of the tube walls and then, after melting, against the wall inertia and the retarding force of the air being compressed within the tube.
